Initial Research Question

Each of the thirty Major League Baseball (MLB) teams plays in one of thirty stadiums or baseball parks.
Of the thirty MLB baseball stadiums, 22 of them are open-air.
We would like to know if changing climate and weather patterns might have an effect on either team performance or game attendance.
